Service Introduction

With the development of the vehicle industry and the improvement of the manufacturing requirements, vehicle enterprises have higher requirements for measurement and calibration. Nonstandard and non-timely measurement bring greater risks to the instruments and equipment, including:

Management: make it difficult to standardize management of instruments and equipment;

Quality: lead to wrong judgment in research due to inaccurate data of vehicle production quality;

Efficiency: Reduce production efficiency and quality, resulting in failure to pass the examination of vehicle announcements;

Review: relevant departments fail to pass the factory examination, leading to complicated formalities.

Test Cycle:

5 working days
